Hazardous and Special Products

Read our Frequently Asked Questions about the HSP Program here.

The Hazardous and Special Products (HSP) Regulation under the Resource Recovery and Circular Economy Act, 2016 (RRCEA) designates automotive materials (oil filters, oil containers and antifreeze), solvents, paints and coatings, pesticides, fertilizers, mercury-containing devices (barometers, thermometers and thermostats) and pressurized containers (non-refillable pressurized containers, refillable pressurized containers, refillable propane containers), under Ontario’s extended producer responsibility (EPR) regulatory framework.

EPR makes producers accountable for their products and packaging once consumers are finished with them; sets mandatory and enforceable requirements for resource recovery; and gives producers choices for resource recovery services in a competitive market.

As of October 1, 2021, following the wind up of the Municipal Hazardous or Special Waste (MHSW) program operated by Stewardship Ontario on September 30, 2021, HSP producers are individually accountable and financially responsible for requirements set out under the HSP Regulation.

Materials included in the regulation:

Category A

  • Oil filters
  • Non-refillable pressurized containers

Category B 

  • Refillable pressurized containers
  • Antifreeze
  • Oil containers
  • Paints and coatings
  • Solvents
  • Pesticides

Category C

  • Mercury-containing devices
    • Barometers
    • Thermometers
    • Thermostats

Category D

  • Fertilizers

Category E

  • Refillable propane containers

Mercury-containing devices were not designated under the MHSW program and are new materials designated under the HSP Regulation.
